One of the factors as to whether a wooden coaster survives an earthquake relatively unscathed is due to how well it's built, obviously. Wooden coasters tend to flex, being that they're made of a flexible material, but they too can buckle and break, depending on their design and how well they're built, and how the ground moves beneath them.
GhostRider at Knott's has almost as much wood in it as Colossus, despite being only a single track coaster vs. the dual tracks of Colossus. It was built that way because of California earthquake building codes. But that doesn't necessarily mean that should a large quake hit the area that GhostRider will emerge without major damage. Again, it depends on many different factors.
